GENTRIFUGAL SUGAR-MACHINE.

Specication of Letters Patent.

Patented dan. 26, 19t 5.

Application led December 20, 1913. Serial No. 807,858.

To all whom 'it may concern Be it known that I, CHARLES KIRCHNER, a citizen of the United States, residing at Sugar, in the county of Fremont and State of idaho, have invented certain new and useful lmprovements in Centrifugal Sugar- Machines, of which the following is a specification. 1

My invention relates to improvements in centrifugal sugar machines, and refers particularly to means for moving the stop to permit the plow or scraper to be swung into position for cleaning or scraping the casing of its accumulation.

The main object of my invention is the provision of means adapted to be operated by the gate or cover of the receptacle,y which will move the stop out of the path of movement of the plow or scraper, and permit it to perform its desired function.

Another object of my invention is the provision of means of the character and for the purpose stated which will operate instantly upon the application of the discharge cover, which will instantly be returned to normal position, and not become accidentally released, and which will be the embodiment of simplicity, durability and inexpensiveness, and which will be thoroughly eflicient and practical in every particular.

To attain these objects, my invention consists in certain details of construction, combination and arrangement of parts, substantially as shown, described and claimed herein.

Figure 1 represents a front elevation of portions of a centrifugal machine equipped with my improvement, the parts being in normal position. Fig. 2 represents a sectional view on line 22 of Fig. 1. Fig. 3 represents an enlarged sectional view of the stop and retaining means forming the prini cipal part of my invention.

Referring by numerals to the drawing, in which similar characters of reference designate corresponding parts in the several views: The numeral 1 designates the casing, 2 the shell or receptacle therein having the discharge opening 3, 4 the cover or gate for the discharge opening, 5 the driving shaft, 6 the mounting or hanger for said shaft, 7 the driving pulley on said shaft, 8 the shaft carrying the plow or scraper 9, and 10 the swinging frame in which the shaft carrying the scraper is mounted, ll.

the belt guide, secured in proper relation to the driving pulley by connecting rods 12, one end of which is secured in the mounting at 13, and the other end in the brackets 13; secured upon the belt guide 11. The parts referred to are of well known construction and in connection therewith my invention is employed. Upon one of the connecting rods 12, is secured the block or head 14:, in one side of which is mounted the stop bolt 15, having a head 16, and connected thereto the coil projecting spring 17, which spring acts to force the stop bolt outward, in which position it is locked by the spring actuated retaining bolt 18. This retaining bolt is mounted in a passage 19, of the head and its inner end 19 engages a slot 20, in one side of the stop bolt and locking bolt in outward position. To keep the bolt from rotating upon withdrawal of retaining bolt 19, I employ the keeper 21, which has its inner portion engaging a slot 22, in said stop bolt.

The construction referred to is seen most clearly in Fig. 3, which shows the parts in normal position, the stop bolt being retained outward and being in the path of vmovement of the swinging frame 10, which carries the plow or scraper, as shown in Fig. 2. For the purpose of releasing the stop bolt and allowing it to be pushed into the head, I connect with the spring-actuated retaining bolt 18, the rod 23, which leads the angle lever 24, which is pivoted at 25 upon the belt guide and has connected therewith at 26, the upper end of the depending arm 27, which arm is guided in the pair of plates 28 and has the hook 29, at its lower end to receive the discharge cover or gate, 4. The rod 23, forming the connection between the angle lever and spring-actuated bolt 18, is made in two parts connected by an adjusting sleeve 30, which serves to take up any wear or play upon the parts, and also serves to adjust the tension of the spring which actuates the retaining bolt.

When the parts are in normal position, the swinging frame with scraper is in the position shown in Figs. 1 and 2, and when desired to bring said scraper into position for use, the discharge gate is placed upon the hook of the depending arm, the gate, by reason of its weight, drawing upon the arm and tilting the angle which pulls upon the connecting rod, draws the spring-actuated bolt out of engagement with the stop and allows it to be pushed backward and out of the path of movement of the shaft 8, mounted in swinging frame, thus allowing the scraper to be brought into position for its operation.

On completion of operation the swinging frame and scraper are returned to normal position and discharge gate removed from hook. Immediately the retaining bolt returns to normal position, locking the fstop bolt in the inward position to which it has been returned by the action of the coil projecting spring.

I claim:

1. In a centrifugal sugar machine, the .combination of a casing, a swinging frame mounted on said cas-ing, a shaft carrying a scraper and mounted in saidframe, a shaft mounting above said casing, said driving shaft depending from the mounting into the casing, a belt-guide `arranged adjacent 4said shaft, a depending arm slidingly mounted on-the belt-guide,-and mechanism connected with said arm and actuated by the movement of the arm to permit the swinging of the 1 scraper shaft past the Vbelt-guide.

2. In a centrifugal Asugar machine, the combination with a casing, a swinging fra-me mounted on said casing and ashaft carrying .a .scraper andmounted insa-id frame, of a hanger above the casing, ashaft bearing in said hanger, a belt-guide supportedffrom said hanger, a ldepending -farm slidingly mounted on said belt guide and having a hook yat vits lowerlend, 4an `angle lever *fulcrumed on the belt guide and having one end connected to-the depending ar1n,vand mechanismI connected withthe other endof said angle lever Vand actuated by thefmovement of the arm to permit the swinging .of the scraper shaft past the belt guide.

3. In combination with a shaft-mounting, a driving shaft, a belt-guide securedto said shaft mounting, an arm depending fromsaid belt-guide and movable therein, an Vangle Copies of this patent may be .obtainedffor lever pivoted to the belt-guide and connected with said arm, a head carried by the belt vguide and sha-ft mounting, a spring actuated .a scraper, of a'hanger above said casing, a

.dri-ving shaft mountedin said hanger and depending into said casing, a belt guide supported-from the hanger, an arm movable inlthe belt-guide and having a hook and mechanism connected with said arm and actuated by the movement of the arm to permit vthe swinging; of the scraper shaft past the .belt guide.

5. In a centrifugal sugar machine, the combination with a casing having a discharge'opening, a-,swinging shaft carrying a scraper, of a hanger above said easing, a drivingshaft mounted in said hanger and depending into saidcasing, a belt `guide supported from thehanger,v anl arm movable in the belt-guide and having a hook and mechanism `connectedwith said arm and actuated by the movementfof the arm to permit the swinging ofthe scraper-shaftpast the beltguide, said :mechanism consisting of yan angle lever carried by the belt guide having one end connected with the arm, ya rodleading from-'its other end, fa retaining bolt connected with .theother end of said rod, a stop bolt engaged by said retaining bolt, and a head supported `by the belt guide and hanger and carrying said retaining and stop bolts.

In testimony whereof I afiiX my signature in-presence of two witnesses.
